Wikipedia tells us:
Televisions in 1928 were radios with the addition of a television device consisting of a neon tube behind a mechanically spinning disk (patented by German engineer Paul Nipkow in 1884) with a spiral of apertures that produced a red postage-stamp size image, enlarged to twice that size by a magnifying glass.
